The most extensively used form of skid now on th; market comprises awooden floor made up 0 boards and lon 'tudinally extendmg ufiper andlower an 1e ars oneach side of the oor sec'uredtoget er to form trussesto sustam the load and to bind together the boards. These angle bars areadjustable toward each other in assembling the skid and, therefore,

readily accommodate the thickness of the boards which, for this reason,do not require s ial fittin The an le bars are adapted sotoholg to ofrandom wid s can be used thus making it'possible very materially toeconomize in the cost of lumber as compared with skids uiring boards ofuniform width.

e present invention provides a skid having man of the advantages of theabove described ouble angle bar truss skid and in addition certainadvantages resulting from the new structure. The skid of the presentinvention has upper and lower truss members, the arrangement being suchthat these members can be adjustable toward each other in the assemblinof the skid to accommodate the thickness 0 the boards, and in thefinishedl sln'd can be integrally connected to form of the load actingdownwardly are resisted I by a horizontal flange reenforced by a verti-'cal flange, and the stresses of the lifting truck acting upwardly arealso resisted by a horilower horizontal flanges. This arrangement a"number of transversely extending ether t e boardsthat boards structureprovides in effect one vertical flange Q which reenforces both the upperand e while economizing metal, et in the assembling operation permitsthe orizontal flanges to'be adjusted relative'to each other toaccommodate the thickness of the particular boards used.

It has been proposed heretofore to use made-up channel bars as sidemembers in the constructure of skids but this r fittinlg the c annel andtherefore increases the cost of the labor of manufacture. Channels ofthe desired shape are also diflicult to manufacture. If they are rolledin the usual equires manner the channel'is ta ered because of the avoidsthe necessity of specially fitting the ends of the boards and permitsthe use of boards of any desired thickness. The metalr members andboards can be expeditiously as sembled to clamp the boards tightly inplace. The present invention provides, also, in the preferredembodiment, an arran ement wherein the metal members entire y. surroundthe floor members thereb confining the floor members entirely withm thecomplete unitary frame.

Referring to the drawings forming a part hereof:

Figure 1 is a perspective view of a skid embodying the invention.

Figure 2 is a transverse sectional view of the same, and

Figure 3 is a sectional detail view showing the welded truss members.

The skid to be described for the pur ose of illustrating the inventionhas a floor w ich ma comprise either one unitary member suc as acomposite board or parallel floor members such as boards 5, togetherwith a unitary metal frame reenforclng the same of the boards to theexact widthof it is then necessary to fit the boards If the channelslies the ends of the boards, and a lower angle bar 7, the horizontalflange of which engages the lower faces of the boards and the verticalflange of which overlies the ends of the.

boards and also preferably overlies the vertical flange of the upperangle bar and is securel welded thereto in the process of assemb 'ng theskid. The arrangement wherein the vertical flanges of the two angle barsoverlap and are welded together substantially continuously throughoutthe whole length thereof is preferred to an arrangement in which theflan es abut each other and are welded together, or the reason that thewelding operation can be performed more satisfactorily in thearrangement first described.

. In the construction shown in the drawings the angle bars are continuedaround the ends of the skid floor to form one continuous framecompletely confining the boards. As shown the frame members consist ofangle bars which are cut to facilitate bending at the corners and-arebent at right angles to form the corners of the skid. The meeting edgesof the horizontal flanges are then welded together along the lineindicated at 8 in Figure 1. The upper frame member may convementlgconsist of two bars bent to U' shape the a tting ends of which arewelded together as indicated at 9, and the lower frame member may besimilarly formed but with the joints sta gered relative to the joints ofthe upper rame member. finished structure, the two vertical flanges ofthe upper and lower angle bars when welded together either at spacedpoints 12 or continuously form in effect one vertical flange whichcooperates with both horizontal flanges to resist bending stressesapplied thereto by the lift truck acting upwardly on the floor membersor by the load pressing downwardly on the floor members.

Legs 10 may be welded to the trusses at 11 or may be otherwise securedif permanently connected legs are desired.

In assembling the skid one frame member may be supported on a suitableassembling bench and the boards 5, which may be of random widths, laidin. The rest of the frame and the legs may then be assembled andsecured. If the legs are welded in position the end portions of theframe serve as tie members to connect the trusses and so prevent 'themfrom separating from each other and from the boards 5. If the legs areIn the bolted in position the boards may be drilled be understood thatthe upper and lower an le bars may convenientl be punched or dn ed to'receive the le bo ts previously to the assembly of the ski The foregoingdescription of a particular .embodiment is illustrative merely and isnot intended as defining the limits of the invention. I

I claim:

2. A portable platform comprising floor members, side members of channelshape embracing the ends of said floor members, fabricated fromassociated metal angle bars having their horizontal flanges engaging resctively the upper and under faces of said oor members and their verticalflanges overlapped and welded together and transverse metal girdersconnected at their ends to the respective channels to form an integralframe.

3. A portable platform comprising floor members, side members of channelsha e fabricated from associated an le bars aving their vertical flangeswelded together longitudinall in such manner as to cause the horizontalanges thereof closely to engage the upper and under faces of the endportions'of the floor members.

4. A portable platform comprising floor members, side members of channelshape fabricated from associated angle bars having their verticalflanges welded together longitudinall in such manner as to cause thehorizontal anges thereof closely to engage the upper and under faces ofthe end portions of the floor members, and transverse metal members forreinforcing the ends of said platform welded to the unitary sidereinforcing bod formed by each of said welded pair of ang e members.
